Wind power is a popular, sustainable, renewable energy source that has a much smaller impact on the environment than burning fossil fuels.

It is an essential source of renewable energy, and its technologies are broadly characterized as either passive solar or active solar depending on how they capture and distribute solar energy or convert it into solar power.

  Bioenergy can contribute to a more secure, sustainable, and economically-sound future by providing domestic clean energy sources, reducing dependence on oil, and revitalizing rural.

Hydro power provides benefits beyond electricity generation by providing flood control. Hydro power provides low-cost electricity and durability over time compared to other sources of energy.
